cast iron

  We adopt Meehanite casting with the specific selection of Inoculation to effectively precipitate flake graphite, which is distributed in ASTM A type. The relevant alloys are added in the casting pieces of cylinder or cylinder sleeve, such as Mo, Cr, P, Ni, Cu, and so on, to stabilize Pearlitic Matrix and finer the crystal structure to make the materials more compact and durable.
  The major mechanical features of cast iron cylinder or cylinder sleeve should achieve:


Tensile strength: 250~300 kgf/mm²
Hardness: HB200~245(HRB 93~100)
